Solution

The correct option is B
acts along the direction of motion
The direction of acceleration is same as the force acting on the body. As we know gravitational force is attracting always and direction of force is always towards the center of another body and g is acceleration due to gravitational force, so direction of force/acceleration will be towards the center of earth.
Also force depends on distance between the two bodies so it is not constant.
So option B is correct.
